Red Wasp Control in Schertz, TX
In Schertz, red wasps tend to get noticed in two ways: a rusty-red, nearly inch-long wasp crawling on a window sill on a warm winter afternoon, or an open gray comb under a carport, shed roof or electrical box that sends out a couple of angry defenders when someone gets close. The first is usually a queen that sheltered for the winter and is not defending anything; the second is a working colony, and if it is near a door or a path it is worth having treated. Call or text (210) 281-1064, or book online, to arrange an inspection.
Older houses, mobile homes and winter visitors #
Schertz has a large share of new construction, but not all of it is new. The Census Bureau's 2020 to 2024 American Community Survey shows 17.4% of the city's homes were built before 1980 (Census ACS). Houses that age have had decades to open small gaps around trim, siding and attic vents.
That matters for red wasps because of how they spend the cold months. Texas Parks and Wildlife describes a fertilized queen wintering in tree bark or in cracks in buildings, then starting a fresh nest in spring. AgriLife adds that overwintering queens bunch up in attics and chimneys and drift indoors on warm days. An older home with loose trim or an open chimney gives them more ways in.
Where red wasps settle on a Schertz property #
The same survey counts 3.5% of Schertz housing as mobile homes. Skirting, carports, porch awnings and the undersides of steps on those homes offer just the kind of covered, dry ceiling these wasps like. LSU AgCenter's list of red wasp nest sites reads like a tour of any Schertz yard:
- Under roof eaves and porch overhangs
- Inside sheds and on the underside of shed roofs
- Electrical boxes, meter covers and A/C disconnects
- Patio furniture, especially the underside of tables and chair seats
- Wood fencing, gate frames and the crossbars of privacy fences
- Tree hollows and any other covered pocket
Check those spots from March through May, while a new comb may have only the queen on it.
How bad is a red wasp sting? #
Bad enough to respect. Texas Parks and Wildlife writes that red wasps can sting over and over, leaving red welts that burn, and that a sting can hurt enough to bring tears. Its 2015 magazine piece put them at 2 on the Schmidt pain scale, described as "merely painful" (TPW Magazine). LSU calls them aggressively defensive once disturbed.
Workers often give a warning first by shaking their front legs at you. Back off when you see it. For anyone allergic, AgriLife notes that a severe reaction typically shows up within 20 to 30 minutes, and that calls for emergency care right away.
Red wasp or some other wasp? #
A red wasp is a type of paper wasp. It builds the same open, umbrella-shaped comb hanging from one stalk, with no paper cover. If the wasps on your comb are brown with yellow marks rather than rusty red, see paper wasp control in Schertz; the approach is the same. A closed paper ball means something else entirely. The red wasp guide covers identification in more detail.
Do's and don'ts for a nest you have just found #
- Do knock down a tiny early comb with only the queen on it.
- Do treat an established nest in the evening, when the wasps are home and quiet, if you choose to handle a small, low one yourself.
- Do wait up to two days for every wasp to die before removing the comb, then wash the spot.
- Don't hang a fake paper nest and expect it to work. LSU found no data supporting them.
- Don't attempt control if you have a heart condition or a venom allergy.
- Don't work from a ladder without protective gear and experience.
